新加坡酒店可唔可以屈蛇?

Normally, it would not have any problem unless you disturb the others and the room nearby complaint your room very noisy.

However, some hotel can allow to add additional bed for extra money. Also, it can have the additiaonl B/F as well if you notify the hotel in advance.

But believe that you a budget traveller (otherwise you will not ask the question), so when you check-in, you shall ask the frontdesk to give you 2 keycards. Then when you return to the room at night, you may separate to get into the room, therefore, nobody will know there was any difference.

唔可以, 我相信任何一個地方都係唔可以, 而且新加坡會比較嚴格, 每個入住者都要登記証件, 到時被發現重無意思啦, 而且加床都係百零元, 無謂博.

please don't do this. if you don't have enough money, then find a cheaper hotel or simply don't go lar
